Figure 2

Multipole excitations in toroidal metamaterials.

Panels (a) and (b) show metamaterial's unit cell with 4-fold (a) and 8-fold (c) symmetry; a = 16.5 mm, R = 2.5 mm, w = 1.2 mm, separation between the centers of the circular cuts is 7.0 mm. Panels (c) and (d) show dispersions of multipolar scattering rates calculated for 4 strongest multipoles induced in 4-fold (c) and 8-fold (d) symmetric metamolecules. Arrows indicate locations of the corresponding transparency resonances.
